Although the eCVT in the Prius is generally leak-resistant, several issues can cause fluid leaks:

Worn-out seals: Over time, the seals around the transmission can degrade, causing leaks.
Loose o r damaged drain plugs: If the drain plug is not properly tightened o r is damaged, it can result in fluid leakage.
Cracks in the transmission housing: Hard impacts o r stress can cause cracks in the housing, which can lead to fluid leaks.
